In France July 4, 1931 3 Claims. (01. 261-92) This invention relates to an apparatus for producing gases used for feeding explosion motors which is designed to advantageously replace the carburetters actually in use.

The apparatus is characterized firstly' by an enclosure through which said air passes and in which are provided a small adjustable fall of gasoline, a mass of water, and means to atomize said-gasoline and a small quantity of water taken from said mass of water.

The apparatus is characterized secondly by a blade wheel upon which the gasoline fall is directed and which is partially immersed in the water, in such a manner that said wheel atomizes both the gasoline and a small quantity of water.

Another characteristic of the invention consists in that the aforesaid blade wheel is driven by another wheel actuated itself by the air drawn in by the motor this last wheel which is secured upon a shaft common to both wheels being placed at the opening of the gas outlet tube so that it also assists the gasification.

Lastly in order to render the gasification more complete a third blade wheel independent of the two others is provided in the interior of the gas outlet channel, it is also actuated by the gaseous stream.

The annexed drawing shows by way of example an apparatus constructed according to the present invention.

Fig. 1 is a longitudinal sectional view of said apparatus.

Fig. 2 is a part sectional view on line A-A,

Fig. 1.

The apparatus comprises a receptacle 1 provided with an inlaid bottom 2 forming a water tank 3. A second container 4 is formed in the upper part of receptacle 1 for the gasoline 5 which may how out drop by drop through an orifice 6 adjustably closed by means of a needle valve 7 provided with a rod which extends to the outside where it carries suitable driving means.

The gasoline flowing out through the orifice 6 is guided by a small tube 8 upon the spiral blades of a wheel 9 slightly immersed in the water in the tank 3. The wheel 9 is carried upon a shaft 10 which carries at its other end a second blade wheel 11. The shaft 10 is supported upon the opposite ends of a squirrel cage structure which the wheel 11.

nected with the motor suction pipe not shown,

there is merely provided in the channel a regulating flap valve operable by any suitable means. The air flows in the receptacle 1 through a self acting valve 16. Water and gasoline filling plugs are provided at l7, 18 respectively. The container 1 is also provided with a spring controlled safety valve 19.

In the pipe 141s mounted a blade wheel 20 which takes up the whole section of said pipe and is formed so as to allow of its being rotated, in the same manner as wheel 11, by the air flowing in the direction shown by the arrows.

Lastly, upon the tube 14 which is made in several parts are inserted filters 21, 22 constituted for instance by wire gauze with the double object of preventing the passage of small drops of liquid which may be eventually drawn along and to prevent back firing.

orifices such as 23 are preferably provided in the upper part of the gasoline container 4 in order to regulate the outflow of the latter through the outlet 6.

The mode of operation is as follows:

The wheel 11 being rotated by the suction air flowing through the valve 16 to the tube 14, rotates the wheel 9, which atomizes both the gasoline dropping upon its blades and the water which it takes from the mass 3. It will be noted here that even when the wheel 9 is no longer immersed in water, it receives the small drops of water thrown off by the jolting of the vehicle.

The atomized water and gasoline are gasifiecl by the air current which draws them along and the mixture is stirred up by the wheels 11, 20 which complete the gasification, so that the motor is effectively fed by gasoline and water vapours the more so that the gaseous stream is heated as usual as its nears the motor.

The apparatus according to the present invention owing to the fact that it does not comprise the use of a carburetter does away with all the inconveniences of the latter, such as choking, getting out of order or the like. It also allows of producing a rational carburation in that at high speed where the quantity of air flowing in the mixture is very great, the delivery of the gasoline being always the same the mixture remains rich, contrarily to that which obtains in existing carburetters where the quantity of gasoline admitted decreases with the lowering of the depression resulting from the full opening of the flap valve 15. I

Gonsidering on the other part that the gasification of the gasoline is perfect there results a great economy of fuel and at the same time an increase of power, which may again be made greater through the presence of steam which gives a richer explosive mixture. Lastly, owing to the oxygen contained in the steam there is no scale deposit in the cylinders, the carbon being thoroughly burned with the oxygen.

While the invention has been shown and described in its preferred form, it will be understood that various changes and variations may be made in the specific structure without departing from the spirit and scope of the invention as defined in the claims.

What we claim and desire to secure by Letters Patent of the United States is:

1. In a carbureting apparatus for motors having a suction conduit, a receptacle partially filled with water and the atmosphere of which communicates with the open air and with the suction conduit of the motor, a rotary blade wheel immersed partially in the water of the receptacle, a fuel reservoir, and means to carry the fuel through gravity and in a regulated quantity from this reservoir onto the blades of said wheel.

2. In a carbureting apparatus for motors having a suction conduit, a receptacle partially filled with water and the atmosphere of which communicates with the open air and with the suction conduit of the motor, a rotary blade wheel immersed partially in the water of the receptacle, a fuel reservoir provided with an opening located at a level higher than the blade wheel, a regulable valve to control the feed of this opening, and a passage from this opening and terminating in the vicinity of the blades of said wheel above the level of the Water.

3. In a carbureting apparatus for motors having a suction conduit, a receptacle partially filled with water, an automatic valve to cause the atmosphere of this receptacle to communicate with the open air, a passage to connect this atmos phere with the suction conduit of the motor, a blade wheel at the entrance of this passage driven rotatively by the gaseous current passing in this passage, another blade wheel driven by the preceding and arranged in the receptacle outside of this passage, this second blade wheel being immersed partially in the water of the receptacle, a fuel reservoir and means to carry the fuel by gravity in regulable quantity from this reservoir onto the blades of said second wheel.
